To all whom it may concern.-

Be it known that I, WILLIs HIRE, a citi-- zen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Envelops, of which the following is a specification.

This invention relates to envelops and has for its object the prov1s1on of an envelop formed from a single piece of material so folded and secured as to provide a plurality securing member 21 adapted to be engaged of se arate pockets or compartments, the speci c arrangement of wh ch 1s that they are adapted to contain different matter,

such as catalogues or circulars, 1t being possible'to use circulars or catalogues of dliferent siz'es, especially as all the compartments are separate.

An important object is the provision ofan envelop of this character which is designed to form part of a new maihng system in which all the desired matter may be sent to an addressee in one cover so that the letter and also the catalogues and other matter will reach their destination at the same time instead of at different times as is an annoying defect in the present system.

An additional object is the provlslon of an envelop of this character which will be 0 very simple and, inexpensive in manufacture, highly efiicient in use, and a general improvement in the art.

' With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and 1llu strated in the accompanying drawlngs in which- Figure 1 is a view of the blank from which the envelop is formed,

Fig. 2 is a view showing the formation of the compartment adapted to recelve first class matter,

' Fig. 3 is a view showing the formation of a second compartment, and

Fig. 4 is a view showing the formation of a third compartment.

Referring more particularly to the drawings I have shown the envelop as formed from a single sheet of material 10 of substantially L-shape and including a relatively large body portion 11 and a relatively narrow elongated portion 12 extending from one edge thereof. The body portion 11 has formed at one corner thereof a flap 13 carrying a securing member 14: adapted to be engaged as hereinafter explained, with a securing member 15. At one edge the body portion 10 vhas formed thereon a mmed flap 16 and the opposite edge of t e body 10 is gummed throughout its length, as shown at 17. The edge of the body 10 at a point spaced slightly from the flap 13, is provided with a concave cut 18.

The elongated strip portion 12 is provided with a plurality of concave cuts 19 and has formed upon one edge a flap 20 carrying a with a securing member 22.

In the-formation of the envelop the end portion of the strip 11 is folded upon the line 23, the flap portion 20 is folded upon the line 24 and the securing members 21 and 22 are engaged. This formation is clearly shown in Fig. 2 and provides a compartment open at the concave cut side for the reception of first class mail matter. This compartment is designated by the numeral 25 in Fig. 2. After this compartment is formed 7 the strip portion 12 is folded upon the line 26 to lie upon the portion 11 and the flap 16 is folded over onto the compartment 25 and secured thereto by the gum. The space between the compartment member 25 and the body 11. constitutes another compartment within which may be disposed printed circulars, a small book, or the like. It will be observed that even after the compartment 25 is in this position access may be had thereto by opening the flap 20. The formation of the second compartment is clearly shown in Fig. 3. After the formation of the envelop has progressed this far, the body 10 is folded upon the line 27 and the ummed edge 17 is secured to the opposite si e of the body 11. This provides a third compartment, as will be clearly evident from an inspection'of Fig. 4, within which may be disposedv a lar er booklet, such as a catalogue or the like. 'Fhe flap 13 is then folded down and the securing members 14 and 15 engaged, whereu on all the parts of the envelop to ether with the matter contained therein will be held properly assembled.

From the foregoing description and a study of the drawing it will be apparent that I have thus provided an envelop from a single sheet of material so cut' andfolded as to provide a plurality of compartments within a single envelop whereby mail matter of different natures and classes may be sent under the same cover.

-While I have shown and described the preferred embodiment of m invention it is of course to be understoo that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention I 3 claim:

An envelop formed from a single sheet of material of substantially L-shape including a body portion, an elongated relativel narrow portion extending from one e ge of said body portion, a flap member formed on the edge of said body portion opposite the direction of extension of said narrow pori tion, engaging fastening member carried by said flap and said body portion, a gummed flap formed on one edge of said body porsecond relatively small compartment, and

said body portion being foldable onto itself with the gummed edge thereof engaged against the opposite edgeand said first named flap being foldable whereby to define a third compartment of relatively lar e size. WILLIS H RE.
